Pouring spout for cans



Get. 8, 1963 R. Y. COOK POURING SPOUT FOR CANS Filed Sept. 25, 1961 INVENTOR.

United Etates The present invention relates to dispensing devices and in particular to a detachable pouring spout for a can or other container.

An object of the present invention is to provide a unitary device tor penetrating a can and serving as a pouring spout.

Another object of the present invention is to provide a pouring spout which is simple in structure, one which lends itself to manufacture in a molded plastic with a steel insert, on presently in use molding machines, and one which is economically feasible.

A further object of the present invention is to provide a dispensing nozzle or spout in which the puncturing element and body, or parts thereof, are so constructed and arranged as to cooperate upon turning the body to deform the punctured wall and tightly, yet removably, seal the ate spout or nozzle to the container without the use of supplemental sealing means or elements, such as gaskets.

With these objects in mind, and with reference to the drawing, a description of the invention follows, in which a prefer-red formof the invention is described, although certain changes and modifications may be made therein if within the terms of the appended claim.

In the drawing:

FIG. 1 is a perspective view of the pouring spout of the present invention, a

FIG. 2 is a perspective view of the cap for the spout,

FIG. 3 is a view in section on line 33 of FIG. 1, and

FIG. 4 is a view, in perspective, showing the device of the present invention installed in a can.

With reference to the drawing, the pouring spout of the present invention comprises a plastic body 10 molded over and around the flared end portion '12 of a steel blade or otherwise rigid member '14 having an arrow head forward end portion 16 projecting :from the body 10.

The exterior wall of the plastic body 10 is provided with threads 18 which are engageable by the internal threads 20 of a cap 22. The body :10 spaced spouts 24 and -26 extending from the one end wall thereof and communicating with the other end wall.

The can penetrating member '14 has shoulders 28, and knife edges 30 on its portion 16 which serve to sever the top of a can, as indicated in FIG. 4, when manual pressure is applied to the body 10*.

*In use, the body 10 is pressed by hand so that the steel blade portion 16 penetrates one end of a can 39 to be 3,106,318 Egg Patented Oct. 8, 1963 2 opened. With a quarter clockwise turn to the body 10', the shoulders 28 engage the sides of the punctured opening and screw the body to a position in which a resilient washer'40 on the adjacent end of the body 10 engages the can 39 and seals the body 10 to the can 39.

In order to provide against accidental spillage, the cap 22 is screwed on the body 10 to seal the spouts 24 and 2 6 which ordinarily serve as an air inlet and a liquid outlet, respectively.

What is claimed is:

A pouring spout for cans of the character described, comprising a cylindrical plastic body aving external threads and flat end walls, a steel blade having one end embedded within the said plastic body, the embedded end having the plain form of a frustrum of a cone, and the other end of the said steel blade projecting outward beyond the said plastic body, and terminating in a plain form configuration of a triangle adapted to pierce any can in one end of which the said outwardly extending end of the said steel blade is inserted, and a pair of equally spaced and parallel spouts extending from one flat end wall of the said cylindrical body and communicating with the other end wall of the said cylindrical body, each one of the said spouts being on one side of the said steel blade, and both spouts extending beyond that one of the end walls that is opposite the outwardly extending end of the said steel blade which pierces the top of any desired can, and a resilient washer adapted to that end of the said cylindrical plastic body from which extends the said steel blade,

, the said resilient washer being between the top of the can and the said cylindrical body, thereby preventing leakage of material from the said can as the material flows through the said spouts in the said cylindrical plastic body and a cap having internal threads, the said cap being screwed onto the said external threads of the said plastic body, and engaging the open ends of the said spouts when the said pouring spout is not in actual use.
